Abstract
An information handling apparatus and screen display control method for appropriately controlling a screen display when a changed output destination for a display signal is selected from among a plurality of display devices having different resolutions. The method, which switches a display signal output destination between a plurality of display devices connected to an information processing apparatus, has (a) a first resolution control step of examining a physical maximum resolution for each of the plurality of display devices that are connected to the information handling apparatus, and storing the examined physical maximum resolutions respectively; (b) a second resolution control step of determining a maximum resolution (maximum static resolution) that is used for the allocation of a screen buffer; (c) a selection step of designating one of the plurality of display devices as an display signal output destination in accordance with an instruction from a user; (d) a third resolution control step of determining a maximum resolution (maximum dynamic resolution) in accordance with a display ability of software for which a screen display is currently being performed; and (e) a resolution determination step of setting a physical resolution of the display device designated, at the step (c), as the display signal output destination, to a lower resolution of either the physical maximum resolution stored at the step (a) or the maximum dynamic resolution determined at the step (d).
